An unhandled exception of type 'System.Messaging.MessageQueueException' occurred

Hi,
I am trying to set up a VERY simple project to send message to MSMQ from .Net using C#. When I run my code it throws an exception

"An unhandled exception of type 'System.Messaging.MessageQueueException' occurred in system.messaging.dll"

I can only find one other link from Google ( http://www.dotnet247.com/247referenc.../14/73719.aspx )where this has occured. Can someone help me out here. I find it hard to believe that apart from myself only one other person has seen this issue.


Source Code:
public void SendMessageTransactional()
{


if (MessageQueue.Exists(@".\Private$\TestQueue"))
{
// Connect to a queue on the local computer.
MessageQueue myQueue = new MessageQueue(@".\Private$\TestQueue");

// Send a message to the queue.
if (myQueue.Transactional == true)
{
myQueue.Send("My Message Data.", "a Label");
return;
}
}
}

I can send messages to the queue from VB6, so the queue itself is fine. The queue is private, absolutely nothing odd about it. I have created several queues all the same result from dotnet.

Any help is greatly appreciated, this is very annoying

Not having much experience using .NET and MQ I decided to take a stab at this one. I couldn't get it to error out. If it makes a difference, I'm on a Win2K Advanced Server(SP4) that's not a domain controller and is part of a workgroup, so I can only have private queues. This is the code I used to read and write to the queue:

PHP Code:

---

using System;
using System.Messaging;

namespace MessageQueueTest
{
    public class MainApp
    {
        public static void Main(string[] args)
        {    
            //Connect to a queue
            MessageQueue sender = new MessageQueue(".\\Private$\\temp");
            //Create a new message
            Message msgSent = new Message("Hello World!");
            //Set the type of formatting to use for the message
            msgSent.Formatter = new BinaryMessageFormatter();
            //Send it to the queue
            sender.Send(msgSent);
            //Create another connection to the same queue
            MessageQueue receiver = new MessageQueue(".\\Private$\\temp");
            //Try to receive the message
            Message msgReceived = receiver.Receive();
            //Set the type of formatting to use for reading the message
            msgReceived.Formatter = new BinaryMessageFormatter();
            //What was in the message?
            Console.WriteLine(msgReceived.Body.ToString());    
            Console.ReadLine();
        }        
    }
}
